Ngokusho kwemithombo yezimboni eTaiwan, okuyinto Isisetshenziswa se-inthanethi i-DigiTimes, umkhiqizi wenkumbulo waseShayina i-ChangXin Memory Technologies (CXMT) imatasatasa ilungiselela imigqa yokukhiqiza ngobuningi benkumbulo ye-LPDDR4. I-ChangXin, eyaziwa nangokuthi i-Innotron Memory, kuthiwa isungule eyayo inqubo yokukhiqiza i-DRAM isebenzisa ubuchwepheshe be-19nm.
Ukuze kukhiqizwe inkumbulo yezentengiso ebhizinisini layo lokuqala le-300 mm, i-ChangXin bekufanele engxenyeni yokuqala ka-2019. Maye, lokhu akukenzeki. Kepha ukuqala kokukhiqizwa kwama-chips e-8-Gbit DDR4 LPDDR4 kuzohambisana nokunwetshwa kwamandla kuma-silicon wafers angama-20 ayizinkulungwane ezingama-300-nm ngenyanga. Umthamo omkhulu wemigqa ebhizinisini le-ChangXin ufinyelela ku-125 300 300 mm wafers ngenyanga. Kodwa lokhu akuwona umkhawulo futhi. Le nkampani ithe izoqala ukwakha imboni yesibili ngonyaka ozayo ezocubungula ama-memory wafers angu-XNUMXmm.
Ngesikhathi esifanayo, lo mkhiqizi waseShayina angase abhekane nezinkinga zohlobo oluhlukile. Masikhumbule ukuthi inkampani yokuqala yaseShayina eyayizoqala ukukhiqizwa ngobuningi benkumbulo ye-DRAM kwakunguFujian Jinhua. I-USA ngokuvinjelwa kokuthenga izinto zokukhiqiza kozakwethu baseMelika. E-Taiwan, bakholelwa ukuthi i-ChangXin izobhekana nezinkinga ezifanayo ne-Fujian. Ngaphezu kwalokho, yaqasha onjiniyela abaqeqeshiwe benkampani yangaphambili yaseTaiwan ye-Elpida yaseJapan, ibhizinisi layo lathathwa yi-American Micron. Abahlaziyi balindele izimangalo ngokumelene ne-ChangXin ezivela eMicron kanye nezijeziso uma uhlangothi lwaseShayina lungaphenduli.
Ngokuhambisanayo, i-ChangXin ithuthukisa inqubo yobuchwepheshe yokukhiqiza inkumbulo ngamazinga angu-17 nm. Ukuphothulwa kwentuthuko kulindeleke ngo-2021. Mhlawumbe, isitshalo sesibili se-ChangXin sizoqala ukusebenza ngokukhiqiza amakristalu e-DRAM ngalawa mazinga. Ngaphandle uma kunjalo, unswinyo lwaseMelika kanye namaqhinga kaMicron kuba isithiyo esingenakunqotshwa endleleni yakhe.
